EventSchemaTraceListener Constructor (String, String, Int32, TraceLogRetentionOption, Int64, Int32)

EventSchemaTraceListener Constructor (String, String, Int32, TraceLogRetentionOption, Int64, Int32)

Initializes a new instance of the EventSchemaTraceListener class with the specified name and specified buffer size, using the specified file with the specified log retention policy, maximum size, and file count as the recipient of the debugging and tracing output.

Namespace:  System.Diagnostics
Assembly:  System.Core (in System.Core.dll)

public EventSchemaTraceListener(
	string fileName,
	string name,
	int bufferSize,
	TraceLogRetentionOption logRetentionOption,
	long maximumFileSize,
	int maximumNumberOfFiles


Type: System.String
The path for the log file.
Type: System.String
The name of the listener.
Type: System.Int32
The size of the output buffer, in bytes.
Type: System.Diagnostics.TraceLogRetentionOption
One of the TraceLogRetentionOption values.
Type: System.Int64
The maximum file size, in bytes.
Type: System.Int32
The maximum number of output log files.


maximumFileSize is less than bufferSize.


maximumFileSize is a negative number.


maximumNumberOfFiles is less than 1, and logRetentionOption is LimitedSequentialFiles.


maximumNumberOfFiles is less than 2, and logRetentionOption is LimitedCircularFiles.

For performance considerations, bufferSize and maximumFileSize should be multiples of 1024 bytes. maximumFileSize is not an absolute value; it is a threshold that can be exceeded up to the size of the last message.

The following code example demonstrates how to use the EventSchemaTraceListener constructor. This code example is part of a larger example that is provided for the EventSchemaTraceListener class.

//ts.Listeners.Add(new EventSchemaTraceListener("TraceOutput.xml", "eventListener", 65536, TraceLogRetentionOption.LimitedCircularFiles, 20480000, 2));
ts.Listeners.Add(new EventSchemaTraceListener("TraceOutput.xml", "eventListener"));
